ROAD-RING ATTACHFENT FOR- TRACTION WHEELS.

Application led April 2, 1925.

To all whom-t may concern:

Be it known that we, HENRY D. MOORE and WILLIAM C. F RY, citizens of the United States ot America, residing at Hubbard, in the county ot Marion and State oi Oregon, have invented certain new and Vuseful lmprovements in Road-Ringy Attachments for Traction lNheels, of which the following is a specifica-tion.

'lhis inventionrelates to road ring attachment for traction wheels.

rlhe primary object of this inventionV is to provide a ring structure capable of being used on traction wheelshaving traction increasing lugs, ribs, or other projecting elements, such as those formed on tractor wheels, which would damage city roadbeds or pavements, for preventing the lugs or ribs from engaging said roadbeds while traveling thereover; said ring structure being capable of being quickly and easily made inoperative without necessitating the removal ot the same from the wheel.

Other objects and advantages of the invention will be apparent during the course of the following descript-ion.

In the accompanying drawings forming a part of this speciiication and in which like numerals are employed to designate like parts throughout the same,

Figure l is a fragmentary side elevational view ot a tract-ion wheel equipped with the road ring structure embodying this invention,

Figure 2 is a bottoni plan view ot the structure shown in Fig. l, and 'further illustrates th-c road ring in its operative position,

Figure 3 is a similar view to Fig. 2 but illustrates the road ring in its inoperative position,

Figure a is a transverse sectional view taken upon line IV-IV of Fig. l, and

Figure 5 is a transverse sectional view taken upon line V-V of Fig. 3.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of this invention, the numeral 5 designates the tread portion ot'. a wheel having any conventional form of supporting means, such as the spokes 6. This tread portion 5, in many conventional forms ot traction wheels, such as those used on tractors, is provided with a plurality of traction increasing elements 7 which may be in the :torni of lugs, ribs, or any other suitable Serial No. 26,168.

elements which will proj ectirom the periphery or" the tread portion 5.

The road ring attachment embodying this invention consists o1E a plurality of similar, substantially trisingularly-shaped segments 8 -which are slightly curved longitudinally, as best illustrated in Figs. l and 5. Each one ot these ring segments is provided with an independent fastening means which may be in the form ot a bolt 9 having a spring asher lO and a nut ll suitably-mounted thereon. These fastening bolts 9 are intended to be provided with squared heads l2 receivable within similarly-shaped counter sunk portions 13' formed in the said segments and project through suitable openings lll in `vthe tread portion 5 ot' the traction wheel.

lt will be noted' by inspecting' Figs. l to 3 `inclusiver that the ring segments are positioned one between each adjacent pair ol' traction lincreasing elements 7. The convex surfaces of these ring segments may be formed perfectly plain or smooth, as illustrated in Figs. l to l inclusive or may be roughened or corrugated as designated at 8a in Fig. 5.

The operation of this road ring attachment may be described as follows To form the ring illustrated in Figs. l and 2, with the segments cooperating with each other to protect the traction increasing elements 7 for preventing them from damaging a city roadbed, `or the like while traveling over the same, the segments 8 are arranged as best illustrated in Fig. 2 with their angularly arranged end edges Sb engaging each other. The nuts ll should then be tightened upon the bolts 9 for clamping the segments 8 against the outer edges of the traction increasing elements 7.

To uncover the traction increasing elements 7, or for permitting the same to be used while the traction wheel is traveling over soft ground, the nuts l1 should be loosened upon the bolts 9 for permitting the segments 8 to be partially turned for allowing them to be moved' radially inwardly of the traction wheel to be arranged between adjacent pairs ot traction elements and in engagement with the tread portion 5 of the traction wheel. rlhe nuts 11 may their be tightened upon the bolts 9 for retaining the ring segments 8 in the positions illustrated in Figs. 3 and 5.

It is to be understood that the forms oi" llU this invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit oi' the invention or the scope of the subjoined claims.

Having thus described the invention, we claim l. ln a device of the type described, the combination with a wheel` having spaced traction increasing elements projecting trom its periphery, o1. a. segmental ring structure continually carried by said wheel and capable oit being arranged to prot-ect or expose said t 'action increasing elements.

2. in a device ot the type described, the combination with a wheel having spaced traction increasing elements projecting from its periphery, o' a plurality of segments carried by said wheel, said segments being capable o1 being arranged to lie between 'the traction increasing elements to expose the same or of being arranged to forni a continuous ring to protect the same.

3. ln a device ot the type described, the combination with. a wheel having spaced 'traction increasing elements projecting from its periphery, o a plurality of curved segments carried by said wheel, said segments being capable of being arranged to lie one between each adjacent pair of traction increasing elements to expose the same or of being arranged to forni a continuous ring outwardly of said elements to protect the latter.

i. In a device of 'the type described, the combination with a wheel having spa-ced traction increasing elements projecting from its periphery, of a plurality of curved segments carried by said wheel, said segments being capable of being arranged to lie one between each adjacent pair of traction increasing elements to expose the same or of being arranged to form a continuous ring outwardly ot said elements to protect 'the latter, and 'further being of similar, substantially triangular-sha-pe, and means for independently fastening the segments -to said wheel.

5. ln a device of the type described, the

nut structure for independently fastening each segment to said wheel.

In testimony whereo'l we ax our signatures. v
